To all wz-om i2 indy concern:

v l Be it. lrnovvn that I, WILHELM VIELANDT,

machine, which is well adapted for dredging soft. moor-peat not capable of sustaining heavy pressure. F or this reason the machine is constantly advanced, and excsvntcs. while moving, an inclined trench by a laterelly inclined dredging erin so that there is no risk of the bog yielding under the track of the machine at the place of operation. Thc dredging arm is laterally inclined, its upper end being suspended from a. rotatable framework mounted. upon the train, so that it is arranged in a plane substantiilly at right angles to the directionA of travel. Owing to the inclination of the erm, the use of n second supporting frame is obvieted Furthermore, the machine is so constructed, that it will cnt the peat into e plurality of steps having sloping banks, so that a collapsing of tile moor ground is not liable to oc our. The lst-eral inclination of the dredging arm enables horizontally extending jbs to be dispensed with, as the heavy dredging arm is loczxtcd close to the train and is pivotnlly suspended thereon. Also the masses which have been dredged, are not only raised, but are at the same time conveyed inward over the trein, without a special horizontal conveying device, the weight oli such transporting device being thus eliminated. Finally, the lateral inclination of the dredging arm, permits a. pecifliar move,- ment of the knives, so that they act on the peatnot only vertically, but also with a cuttingmovement in the direction of their length :is they travel inward.

In the accompanying drawings: Figure 1 is an end view of my improved dredging machine; Fig. .2 a plan thereof; Fig. 3 a. side view; Fig. 4 a detail of the driving means for the dredging tumblers, and- Fig. 5 a side view of the sawing device.

l, 1b, and 1 designate a number of cars which nre coupled to form a train moving on track 2. Car 1b, supports n frame 3, .to which is connected the upper end of a laterally inclined dredging arm 4. The dredging arm sup )erts an endless conveyer carrying .the-dre ging scoopsA 5, and is held in po- Sneeicstifm ci Letters Patent.A

l sition by braces 6 and 6", which connect it: lower end with cars lc and 1*, respectively. The knife edges of scoops 5 pass through the peat bed simultaneously with an upward and. longitudinal movement, so as to sever the peat block by a drawing cut. Back of arm 4, there are mounted on car l, a pair of plowsliares 1U which are adapted to throw been previously excavated by the scoops. In order to show the lower end of the dredger, the carthroof at l2 has been omitted in the cated in front` of the dredging arm, in lieu of being arranged tinck thereof. The motor i3 mounted on car l", serves to irive the train und to simultaneously operate the conveyer chain carrying the scoops 5. In front of plow-shares 10 there is carriedb cnr lb, a sew 14 operated by aycranlr l5 whic is mounted upon one of thek car-axles 16. Crank 15 engages the slot 29 of e. saw holder :28, and thus imparts u rcciprocativc movemeut to the latter. In this way the saw will sever the peut fibers, or other impediments, which would be apt to obstruct the advance of the plow-shares. i

. In order to horizontally guide Scoo s 5, notwithstnntliug the lateral incline o the dredging-erm.' l pretlel'ably arrange the two couver chains 1S) :mti 20, as shown in Fig, '-l. Chain. l2) runs over Wheel E21, while cham 2O runs over ivheel 22, the latter being rotated with the same speed as wheel 21 by ineens of n chain drive 23. Thus the cutting ed' es of the dredger knives are arranged, substantially horizontnkso that durin the excavation cach of them performs :in ob ique movement indicated b v the arrow 7, this movement resulting from the vertical movement 8, which effects the cutting pro r, and from the horizontal movement 9.

A peat dredger com )rising a^traveling frame, a laterally incline dredging arm depending thcrcfrom, an endless conveyor movable along said arm and com rising parallel chains. and scoops secured obliiquely to said chains and having cutting edges that are constantly maintained in a. horizontal position, said scoops bein adapted to work in the direction of the of the dredger.

ln teetnnony whereof I have hereunto adapted to travel continuously during the excavation, a dredging arm depening therefrom and extending laterally to the direction of tra vel, an endless conveyer mov- 5 able along;r said arm and comprising parallel signed my naine this 30th day of August chains, and scoopa secured obliquely to the 'f 1905), in the presence of two subscribing chains, said' scoops being adapted to penewitnesses.
